It seems that the authorities and the bike-sharing firms are favouring the high-tech measure of geofencing to tackle the issue of indiscriminate parking of shared bikes (Bike-sharing firms to use tech to tackle parking issues; Oct 6).

Perhaps a simpler way could also be considered.

Include the respective firm's contact number on the shared bikes' serial number plates, which are then bolted or riveted onto their frames.

This will allow members of the public to call or message the firm when they encounter haphazardly parked bikes.

The authorities can then mandate that the operator retrieve the bicycle within a stipulated period of time after the call or SMS, say, 48 hours.
